1 DATA CENTER & COOLING SOLUTIONS 2012

2 Typical Energy Consumption of a Data Center Infrastructure 19 Racks Cooling units Cooling %50 Fire protection IT components %35 Raised floor Power Power Distribution 15%

3 DRIVING FACTORS FOR THE NEED OF EFFICIENT COOLING Increasing energy prices Increasing capacity and cooling requirement of blade servers and pizza boxes Rising number of servers Increasing datacenter performance Regulatory requirements Power density is increasing 15% per year By 2011 average kw per rack is above 15kW (up from 1kW in year 2000)

4 Cooling Requirement for some Servers!

5 CHALLENGE IN % 18% 18% 2% 13% 13% 6% 2< kw 2-4kW 4-8kW 8-12kW 12-16kW 20-24kW 24> kw From 1kw (2000) to avg. 15kw (2011) per rack!!

6 Cooling Alternatives

7 Cooling Alternatives *Traditional Perimeter Cooling Thermal load per rack up 5 Kw -Raised floor -Chiller, Closed Control Unit *Innovative Aisle Containment Application Thermal load per rack up 10 kw - Raised floor - Isolation - Chiller, Closed Control Unit

8 Cooling Alternatives *Combination of in row liquid cooling system Front Cooler + Cold corridor -Eliminates Raised floor *Side Cooler: Liquid cooling systems for thermal load up to 30 kw -Side mountable to racks, enables high density cooling

9 Air flow in traditional Systems If the distance from CRAC increases, pressure of air decreases Hot and cold air mixes with each other Non-uniform (uneven) distribution of Cold Air, top of the rack is not sufficiently cooled RESULT!! % 75 of all server failures happens at the 1/3 top section of the racks

10 EFFECT OF DENSE CABELING BELOW RAISED FLOOR

11 PROBLEMS OF TRADITIONAL APPROACH Low return temperature C Short circuit of hot air Small Delta T, high air flow Hot spots C Hot spots CRAC Warm air > 30 C CW temperature C Loss of cold air C Low supply temperature C High Presssure&velocity Balancing required

12 FACTORS TO BE CONSIDERED IN EFFICIENT COOLING Do not move more air than required! Focus on hot spots Do not cool the whole datacenter, just cool the servers only! Maintain strict cold and hot air seperation Obtain a uniform and more controllable closed cooling area Keep the cold air temperature between C instead of C Do not waste energy to cool the hot aisle Use energy efficient alternatives like free cooling

13 SOLUTION: COLD AISLE! High return temperature C Cold Aisle C High Delta T, small air flow CRAC Uniform temp. Uniform temp. Warm air < 28 C CW temperature C C Higher supply temperature C Low velocity&pressure No need for balancing!

14 Loss Of Cold Air COLD AISLE SOLUTION Hot Air Short-Circuits Raised Floor Raised Floor *Newest technology in data center design Cost effective and high capacity cooling up to 10 kw per rack Eliminates the need for raised floor balancing Eliminates hot spots and waste of cold air Easy to operate Min investment, high ROI Energy savings up to 50% Fully scalable, from small to large deployments

51 Coolmanager / Pumping stations Integration of SideCooler or FrontCoolers in an existing infrastructure of waterchillers Save separation of primary and secondary water circuit Redundant pumping station Regulation of water inlet temperatures Regulation of condensing freeness

52 Using the geothermal cooling for the direct rack cooling Space -Checking the location of the drilling based on a geothermal map + permit of the public government 240 -m drilling in flushing drilling method ( 3 x drilling each a 80 mtr. depth / diameter per drilling 140 mm ) -Piping work 3 x 80 mtr. HDPE pipes 32( x 2,9 mm) = 3 double sondes - Covering with clay farina cement suspension -System stability with design with a double circulation pump N+1 (redundant) +UPS - buffered

53 Mode of operation : The SideCooler require an inlet temperature of 14 C, to avoid condensate during operation. In the soil (app. 90 meter. deep) a constant temperature of 11 C exists. The glycol-water returns with app. 11 C from the underground pipe. The supply temperature to the Sidecooler of 14 C is controlled by the three-way- valve. In the SideCooler the water-glycol will gain a temperature of app. 19 C. The closed cycle transfers the heat of the IT equipment to the ground.

60 solar cooling systems Solar cooling systems

61 solar cooling systems Solar cooling systems The sun collectors are equipped with vacuum tubes. The heat is getting collected to a hot water buffertank. The hot water is getting pumped to the absorber cooling machine where through a chemical reaction the warmness would be changed to cooling (near without mechanical power, only a pump.) The cold water can be used for air cooling systems (closed control unit or direct rack cooling systems.)
